Good Morning. I Have A Regal With A 10+ Compression Buick 462, Headers, Convertor, And A .500-lift Ta-cam. What Do I Need To Do To Run A/c?? ?
The accessory brackets from a mid 80s N/A Buick V6 will bolt up to the front of that 455, that will hold the newer style A/C compressor, alternator and power steering pump. The engine wiring harness for a G-body with a Buick V6 engine, can be changed at the C-100 plug (under the windshield wiper motor) that should connect to all the accessories without needing to extend the wires too much. Not aware of the headers causing problems. You may have to find a way to kick up the idle when the A/C compressor kicks in.
